how to delete line number 3 or any line of my csv file ?????????????????

like
test.csv

1.jhon
2.sarah
3.ricky //delete this row of csv
4.martin

Depends, do you want the numbers to follow, or will a simple delete do?

You can:

1. get the contents of the file via file_get_contents().
2. split the contents into an array with explode(), use "\n" as a delimiter.
3. delete the 3rd entry ('2') with array_splice().
4. implode the array using "\n" for the delimiter.
5. save the changes with file_put_contents().

If any of these functions are unfamiliar, look them up in the php.net manual. If stuck, come back, I've got the code, but show your workings first.

Try this.

<?php
$cnt = 0;
if (($handle = fopen("test.csv", "r")) !== FALSE) {
    while (($csvadata = fgetcsv($handle, 0, ",")) !== FALSE) {      
	   $data[$cnt++] = $csvadata;
    }
    fclose($handle);
	unset($data[2]);
}
$fp = fopen('test.csv', 'w');
foreach ($data as $fields) {
    fputcsv($fp, $fields);
}
fclose($fp);
?>
